To atom may Patented Oct. 13, 1925.

mam.- I Beit known thiatil, CHARLES S. 'CLAnKso'N, a citizen of the-United States, and a 'resi dent of Toledo, in the county 'of Lucas and State of ()hio, have made an invention appertainingto. a Dom-lock, which invention is fully set forth the followiifg speci fication.

This invention relates to. door fastening means, and particularly to those of the type intended for use in connection with garage doors.

The object of the invention is the provision of a fastening means of this character which will not only lock a door in closed position, but will also draw it by Wedge action into tight closing position, counteracting any sagging or warping tendency of the door.

The invention is fully described in the following specification, and while in its broader aspect it is capable of embodiments in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in wl1ich,-,

igure 1 is a fragmentary inside elevation of a structure embodying the invention, with the fastening means of one door shown released and that of the other door shown in locked position. Fig. 2 is an end view of the socket member of the lock, and Fig. 3 is a central longitudinal section of such member.

Referring to the drawings, 1 designates the top portion of a door casing, and 2, 2 doors hung in said casing at opposite sides thereof for swinging movements toward and away from each other into closed and open position, as is customery in garages, barns and other structures employing doors of this type.

The locking means comprises a socket member 3 which is secured to the under side of the top portion 1 of the casing adjacent to the freeedge of the door when in closed position. 4 is the movable member of the lock, and in the present instance is in the form of a lever, which is pivoted to the door at 5. The short arm of the lever 4 extends upward from the pivot and terminates in a laterally projecting nose 6, which is preferably of conical form, or with its upper and lower edges at least tapered to a more or less pointed outer end. The nose 6 of the lever is so positioned with respect of .conidal form "door is the oasiliggthe nose .6: freely ehte'rs the iippnat'ian fil'eli 'A'ugii'st it, 1923. senaiirovbshao. f i

to the socket member 3"; that it is 'adafioted I to enter t lieregistering 'socket the eof when the lever is thrown to locking position, as

shownby. the ,leven'on'the left-hand door..-

Thesocketf ofthe member '3 is preferably substantially c'om'pleine'ntal to the nose portion (i-of the levenhnd "if the hanging proper position within socket and locks the door against opening and also against sagging or lateral warping. If the door, when in closed position, sags or is warped so that the nose 6 of the lever does not accurately register with the socket 7 the tapered surface of the lever nose will coact with the side wall of the socket, and, as the lever nose is forced therein, will tend to draw the: door into proper closed position within the casing opening.

If the door is of the double type, as shown in the drawing, the socket member 3 may be made double or in a single piece for both doors.

The long arm of the lever extends down through a guide 8 to convenient operating position and is adapted to be engaged near its free end with a holding means, which secures the lever in any position to which it may be adjusted and constitutes a bar 9 disposed transverse to the lever and having a plurality of perforations 10 which may register with the perforations in the lever to adapt a locking pin 11 to be inserted therein.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications and changes Without departing from the spirit of the claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,-

1. The combination with a door casing and a door swingingly mounted therein, of a socket member fixed to the upper portion of the casing adjacent to the free edge of the door with its socket opening at a side thereof, and a lever pivoted intermediate its ends to the door and having its upper arm provided with a laterally projecting tapered nose portion which is adapted to be moved into the socket of the member and to coact with the socket walls to lock the door in closed position and to prevent sagging and warping of the free edge portion of the door, and means for securing the lever in looking position.

2. The combination with a door casing and swinging door mounted. therein, of a socket member fixed to" said casing adjacent the free edge of the door, a lever pivoted intermediate its ends to the door and having on one arm thereof a laterally projecting, tapered nose which is adapted to be moved into the socket of said member thereby to lock the door in closed position and to prevent sagging and warping of the free edge portion of the door, and means associated with the other arm of said lever for detachably connecting said lever and door thereby to hold the lever in locked position.

3. The combination with a door casing and swinging door mounted therein, of a socket member fixed to said the free edge of the door, a lever p1voted adjacent its upper end to the door thereby to provide a long and short arm, a laterally projecting, tapered nose on said short arm adapted to extend into said socket thereby to lock the door in closed position and in order to prevent sagging and warping. of the free edge portion of the door, a guide on said door for the long arm of the lever, a bar fixed to said door having a plurality of apertures, the long arm having an aper ture for registration with one of the apertures on said bar, and a pin adapted to extend through said registering apertures for locking said lever in the desired position.

In testimony whereof, I'have hereunto signed my name to this specification.

CHARLES S. CLARKSON.
